BindingNavigator: AddItem button saves the form, but does not clear the form for the new Record

Question

I have a Visual Basic project that uses a form to save information to a XML database. The form controls are bound to a DataTableBindingSource and all is fine except the "AddNewItem" button on the BindingNavigator seems to be saving the form. This is not the behavior I expected since there is also a SaveItem button that works great for saving the data to the DataTable. And since I wish to automatically clear the form for a new record after saving, I wrote a routine that clears all the TextBoxes, CheckBoxes, DropDowns, etc… when the SaveItem is clicked. The SaveItem also writes the DataSet to the XML database so no data is lost, but then when I click the AddItem button, it saves the Cleared form over the existing record in the DataTable, so when I click the SaveItem the altered DateTable gets written to the XML Database. Is there any way to grab the control of the AddItem button and alter its behavior so that it doesn’t save the form, or am I not seeing a bigger problem if I did that? I Know I could write my own AddNewItem routine, but the button would be in the wrong place…
